b8455445c5 aggregator: Ensure that the source pad is created as a GstAggregatorPad if no type is given in the pad template
Otherwise we would create a GstPad and that causes invalid memory
accesses later.

9ec55072d2 aggregator: drop duplicated SEEK events
This is similar to what demuxers do, and necessary when multiple
sinks get seeked downstream of the aggregator: if we forward
duplicated seeks upstream, elements such as demuxers may drop
the flushing seeks, but return TRUE, aggregator then waits forever
for the flushing events.

Fixes #276

09909d37bd aggregator: Make parsing of explicit sink pad names more robust
When passing "sink_%d" twice to aggregator before it would create two
pads called "sink_0", because it failed to parse "%d" as integer and
used 0 instead then.

Instead validate that parsing was actually successful and also don't
even try to parse if the requested pad name contains a '%'.

7cfdb23387 gstcheck: Document strcmp used in string cmp macros
strcmp() does not allow the arguments to be NULL, but g_strcmp0()
does, so document that we use g_strcmp0() so that people don't need to
worry about that.

91543bd78d testclock: Allow calling crank with a past entry
At the moment, we can only use crank if the pending entry is in the
future. This patch leaves the clock time to the same point if the
pending entry was in the past. This still execute a single entry. This
will be needed for the jitterbuffer, since as soon as we stop waking up
the jitterbuffer when the timer is reschedule later, we may endup with
such case in the unit tests.

229b4776ea harness: move creating of buffer and event queues to harness itself
By only having it on sinkpad-creation, it is racy to write a test
with a sometimes-pad (like a demuxer) that you want to pull from, having
the pull wait until the pad arrives and the buffer can be produced.

69430dd7ba harness: Make sure pad functions are not called after teardown
For the query function there's a risk that the function may be called
after the harness has been teared down. Since the function accesses a
pointer to the harness via the pad's data, the harness must protect
itself against this.

Event and chain function is also handled for constistency, although
they don't have the same problem since the gstpad.c checks whether the
pad is flushing before calling these.

6d16615093 aggregator: don't try to take STREAM_LOCK on sink pad flush
This was a misguided effort to try and guarantee the buffers of
the sink pads would not change during aggregate, when an upstream
branch is seeked independently, however this is simply incorrect
as downstream has not necessarily been flushed, or the aggregate
function might be waiting to receive buffers on other pads.

4087361da3 aggregator: send flush_stop ourselves if needed
In !159 , we switched to sending flush_start ourselves from the
do_seek implementation. If no flushing seek successfully made its
way upstream, we need to send flush_stop ourselves as well.

c55c61eb84 aggregator: don't hold stream lock when flushing
Releasing a GRecMutex from a different thread is undefined
behaviour.

There should be no reason to hold the stream lock from the
moment aggregator receives a flush_start until it receives
the last flush_stop: the source pad task is stopped, and can
only be restarted once the last flush_stop has arrived.

I can only speculate as to the reason why this was done,
as it was that way since the original commit. My best
guess is that aggregator originally didn't marshall events
and queries to the aggregate thread, and this somehow
helped work around this.

25383eaa5c aggregator: refactor flushing logic
Instead of tracking "pending_flush_*" on the pads and the
aggregator, we now simply track the last seqnum for flush start
and flush stop events on the pads, and use it to determine whether
we should enter or exit our flushing state.

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/977

09141c6e1f Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

1a3bf3234f aggregator: fix flow-return boolean return type mismatch
Not that it matters, since we don't check the return value
anyway. Unclear why the aggregator pad flush function should
have a return value at all really, and perhaps it should be
called reset anyway. Spotted by dv on irc.

36c2fc3bc3 gdb: gst-print add more pad and element information
For elements, this adds all child elements, the state and base/start time:

(gdb) gst-print pipeline
0x5555556ebd20 "pipeline0"
GstPipeline(pipeline0) {
    children:
      fakesink0
      queue0
      videotestsrc0
    state: PLAYING
    base_time: +2:54:36.892581150
    start_time: 0:00:00.000000000
}

For pads, this adds the peer pads and the current task state and the
offset (if not zero):

(gdb) gst-print pad
SrcGhostPad(src, push) {
  events:
    [...]
  peer: vaapisink0:sink
  inner peer: scale:src
}

(gdb) gst-print pad
SrcPad(src, push) {
  events:
    [...]
  peer: queue0:sink
  task: STARTED
  offset: 30000000 [+0:00:00.030000000]
}

It's possible that setcap is installed, but the libcap headers/libs aren't (e.g.

but need the headers of the target). Also removes the need to manually check
for the libcap headers.

ae57b1c76d aggregator: add buffer-consumed pad signal
The signal will be emitted when a buffer was consumed on
a pad, if the newly-added "emit-signals" property has been
set to TRUE.

Handlers connected to the signal will receive a valid reference on
the consumed buffer, allowing for example the retrieval of metas in
order to forward them once an output buffer is pushed out.
